Check the driver side lower dash compartment first, where the main protection unit is installed behind a snap-on cover, giving access to labeled slots and small relays.
Use the label chart on the inner cover to match each position with systems such as ignition, audio, lighting, and climate control, noting amperage values typically ranging from 5A to 40A.
Open the hood to locate the secondary power distribution center near the battery, which contains higher-capacity links for starter motor, cooling fans, and charging circuits.
Inspect each element for a broken internal strip or heat marks, and check contacts for oxidation; always install replacements with identical ratings to maintain proper circuit protection and prevent wiring damage.

Match each slot in the interior electrical module with the printed legend before removal, as incorrect placement can interrupt ignition, lighting, or onboard electronics.
- ACC – accessory outlets and media system
- IGN – ignition switch and engine control
- HVAC – climate control blower and sensors
- AUDIO – radio and amplifier circuits
- WIPER – windshield motor system
- SRS – airbag control unit
In the engine bay, locate the power distribution center near the battery where larger capacity elements and relays are grouped; relays control high-load circuits such as cooling fans, starter engagement, fuel delivery, and headlamps, and each position is marked with identifiers to guide accurate replacement and troubleshooting.
Exact location of interior fuse panel and access behind dashboard trim
Remove the lower driver-side trim panel by pulling from the edge near the door seal, then locate the interior power distribution unit mounted above the kick panel, slightly left of the steering column; access requires no tools if clips are intact, though a plastic pry tool helps avoid surface damage.
The unit sits behind a rectangular cover with a small finger notch; once opened, you will see labeled slots arranged in vertical rows, with amperage ratings printed beside each position, and a small puller tool often clipped inside the cover for removing protective links.
Follow these access steps:
- Turn ignition fully off and remove key
- Open driver door wide for working space
- Grip trim panel at lower corner and pull outward evenly
- Locate protective cover above footwell insulation
- Unclip cover and expose internal layout
Wiring harnesses run horizontally behind this area, secured with plastic retainers; avoid pulling or twisting these lines, as they feed critical cabin systems such as lighting controls, infotainment, and climate modules.
If resistance is felt when removing trim, check for hidden screws near the hood release handle or beneath rubber inserts, as some configurations include additional fasteners that prevent clean removal.
